Please, CNN, don't legitimize Coulter

CNN just featured Ann Coulter reviewing the presidential debating style of Fred Thompson. 
What makes a supposed news outlet decide to use a pundit of her caliber to speak about politics?  With hundreds of informed, educated politic-watchers to choose from, why scrape the bottom of the barrel and pick a person who recently said, "If we took away women's right to vote, we'd never have to worry about another Democrat president. It's kind of a pipe dream, it's a personal fantasy of mine, but I don't think it's going to happen. And it is a good way of making the point that women are voting so stupidly, at least single women."
